Application led December 17, 1917. Serial No. 207,422.

Be it known that I, HARRY C. GEORGE, a citizen of the United States, and a resident ofthe townshipof Morris, in the count-y of Morris, Statek of New Jersey, have invented certain new and useful Improvements in Adjustable Insoles, of which the following is a specication.

The improvements relate to devices adapted to be placed in boots and shoes and to be used for thepurpose ofcorrecting abnormalities of the foot, and particularly to devices of this character which are commonly called insoles. f i

One of the common defects in the human foot is atende'ncy of the heel'to incline toward one side or the other. The physiological reasonsy for this need not be discussed, and the e'ect causing the wearing down" of the heel ofthe shoe and in many cases permanent displacement of the calcaneum or os calcis and deformity of the structure of the instep arch is well understood. Most cases of this kind, if taken in the incipient stages orbefore the abnormal tendency has developed to anyconsiderable extent, may be corrected. )The difficulty is that the tendency though recognized is neglected until the deformityy has progressed to such an extent as to become painful, at which stage complete correction is often. dilicult, if not impossible. It has therefore long been recognized by orthopedists and others who have to do with the correction of foot deformities, and by makers of foot wear and correcting devices that a simplev contrivance adapted-to be adjusted to meet all ordinary cases of the character indicated, which can,

be bought and adjusted by the user to suit his particular condition, is very desirable.

It is the primary object, therefore, of the e of an insole embodying the improvements,

with the parts adjusted to correcta tendency to Wear down on the inside of the heel of thcright foot; Figure 2 is a similar View of the same device with the parts adjusted to correct the same tendency toward the other side; Figure 3 is a Side elevation `of the device as illustrated in Fig. l; Figure Il is a verticalsection on the line 4 4 of Fig. l, and Figure 5 is a similar sectionon the line 5 5 of Fig. 2; Figure 6 is a detail of the removable tongue by which the adjustment to support one side of the foot to the other 1s made.

The insole consists of two pieces of flexible material A and B, preferably leather, cut to it the inside of the sole, of a shoe and to coincide therewith. These two pieces, forming the insole proper, extend from the heel to the ball of thefoot, or a little beyond that point. The design being .to have the insole extend ,from the calcaneum to the anterior metatarsal zone. They are secured together by two rows of stitches C and D extending from the forward part of the insole at the sides to a point near the middle of the heel and forming a V, and are also secured bv the marginal stitching E and F crossing the for the reception of the tongue G, or any other similar device for adjusting' the elevation of the upper surface of the insole. The pockets are indicated by the letters H, l and J, the former being the metatarsal pocket and the two, latter the heel pockets.

The vtongue G is of peculiar forni, on account of which it is adapted to be used for the purpose of correcting the heel deformity in question on either side of either foot. will be seen that it consists of a heel portion G and a tongue portion G2 extending therefrom, a notch or recess G3 being formed in one edge at the junction of the heel and tongue portions and adapted to receive' the point formed by the merger of the rows of stitches C and I). As this recess and the point of the stitches are located centrally the adjusting member (i may be reversed and moved from one side to the other as desired, and will coincide with the contour. of the insole and be securely held in position in both positions.. It is tapered from the back I Itk of the heel portion to the tip of the tongue portion, and from its outer edge toward its inner edge so that in both positions the outer edge ofthe. insole is elevated and the greatest elevation is at the back or extremity of the heel. v

The stitchesE and l-l also have a part in the holding of the adjusting piece G inasmuchas the tip of the tongue enters between the rearwardly extendin part of these stitches and the stitches and D, and is held thereby against lateral movement. In this mannerA` when. the adjusting piece is placed in position on either side ot' the insole it is locked by the engagement of the tip of the tongue just described and of the notch G3.

From the foregoing description it Will be seenthat an insole consisting of an insole proper and an adjusting insert is provided, which may be used to elevate `one side of the heel or the other, by simply removing, reversing and reinserting the insert, and that when this is done the parts are held securely in position. The usefulness of thel device.v however, is limited to insoles sold in pairs or for the right or the left foot, as it Will be apparent that one insole With the adjusting device may be used on both teet alternately. This is done by simply reversing the insole and applying it to the opposite foot, in which position it may by the adjustment of the insert G be used to support one side of theheel or the other. This enables the manufacturer to make and the dealer to keep in stockvan insole which may be sold singly for either foot or in pairs with a. single insert for each insole, which meets all the requirements andvis securely locked in all positions. i

vThe forward or metatarsal pocket H may beused to receive any elevating device desired, and it will be apparent that the adjusting device (l may be inserted therein to support one side or the other, or that a different device may be employed. To this end short, rows of stitches K and L have been provided in the said pocket H, uniting the two ieces A and B, and providing means for holding Wedges or other adjusting devices against lateral movement, by having them passed' between the said stitches are held by one or the other in manner similar to the engagement of the notch G3 by the point of the stitches C and D.

'What I claim is:
